The physical aspects of anxiety got me too. Please speak to a DR. I was given AD, which helped but more importantly they gave me something to help me sleep. Once I could actually get a good nights sleep I felt so much better and able to handle the rest much better.
I am so sorry that you have to go through this a second time, but you will make it through.
Take good care of yourself, and you will be better able to look after your family and future.
